2008 Toyota Tacoma Parts Questions & Experts Answers

• Q: How does the Air Bag Supplemental Restraint System (SRS) function and what are the essential service procedures to follow on 2008 Toyota Tacoma?

  A: A Supplemental Restraint System (SRS) on the vehicle consists of driver Air Bags together with front passenger Air Bags alongside side Air Bags and curtain shield Air Bags but requires correct servicing procedures to stop accidental Air Bag deployment that could cause severe accidents. All service operations need a minimum waiting period of 90 seconds after the ignition switch has been moved to LOCK and the negative (-) battery terminal cable has been removed because the SRS has an emergency power supply. The Steering pad and front passenger Air Bag assembly together with various Air Bag sensors must never experience exposure to either hot air or flames. The occupant classification ECU requires initialization whenever the replacement of this ECU occurs or new accessories get installed or when installing or uninstalling the passenger seat along with a situation where the seat occupancy indicator shows an OFF state while unoccupied or following an accident. Check collision-related Diagnostic Trouble Codes before disconnecting the battery and thoroughly check all SRS components whenever any car accident happens. Always refrain from using SRS parts thatoriginated from different vehicles while replacing damaged components with fresh replacements. When inspecting electrical connections use a high impedance volt/ohmmeter with a minimum 10 kOhms/V to diagnose electrical problems and inspect any SRS component according to information labels. The schedule for SRS work completion requires a check of all warning lights related to SRS components. Note down the memory data from each system before powering off the battery and conduct system resets after finishing maintenance tasks. Engineers performing center Air Bag sensor and front Air Bag sensor handling must disconnect seven different Air Bag sensors including the center Air Bag sensor assembly and four front Air Bag sensors before starting their inspection. It is necessary to wait for 90 seconds after removing the negative battery terminal to replace Air Bag sensors and adjust doors featuring side Air Bags. Running the engine at less than 2000rpm for at least 1 minute after reattaching the negative battery terminal prevents clutch automatic disengagement from occurring. Also maintain the sensors secure and intact throughout the work. Accident checks involve both monitoring SRS warning lights and accessing DTCs through Techstream monitoring. Deployed Air Bags must be replaced following accident checks of installation conditions. The yellow SRS connectors come with reliability features that both avoid incorrect wiring and establish a safe locking system. The SRS system launches automatically after sensing a collision impact stronger than the specified threshold thus activating the driver and front passenger Air Bag squibs to activate their deployment. The process of disconnection and connection for Air Bag connectors requires the use of a screwdriver to release locks together with audible clicks of secure connections while refraining from touching sliders during the procedure.
